The fact that the accused does not understand the language in which the trial is being conducted is a fact well known to the accused and it is for him or his counsel to take the initiative of bringing it to the notice of the Court at the earliest opportunity. If he does not claim the right at the proper time before any damage is done, he may not be able to have a valid complaint afterwards, for example on appeal. Where the accused person refuses to inform the Court that he does not understand English Language, it will be too late for him to seek protection under Section 36(6)(e) of the Constitution to have his conviction set aside through the backdoor.
